“…It is assumed that, during the potential cycling, NiHCF is formed with simultaneous insertion of K þ . These two sets of voltammetric peaks were explained by the existence of two predominating forms of NiHCF [26]. The more positive set of peaks is usually attributed to K 2 Ni[Fe 6 ] that are K þ -rich and more strongly paired by potassium ions.…”

The layer-by-layer (LbL) self-assembly process has become an important tool in the fabrication of nanostructured devices for electrochemical applications, especially in those cases where control at the molecular level is required. In this paper we present a system based on electroactive nanostructured membranes (ENM) with ITO-PVS/PAMAM-Au LbL electrodes, in which a redox mediator (Me) is electrodeposited around the Au nanoparticles to form an ITO-PVS/ PAMAM-Au@Me system. The redox mediators used were Co, Fe, Ni and Cu hexacyanoferrates. The 3-bilayer ITO-PVS/ PAMAM-Au@Me system was characterized electrochemically by cyclic voltammetry and electrochemical impedance spectroscopy. All hexacyanoferrate modified electrodes showed electrocatalytic activity towards hydrogen peroxide, thus demonstrating that this new approach can be used in biosensors and nanodevices, where a redox mediator is required.

“…The peaks at ca. 0.45 and 0.29 V vs. SCE are due to redox state of NiHCF, which can absorb and release potassium cations during cycle potential [43], respectively. It was seen from Fig.…”

Sulfonated carbon nanotubes (sCNTs) were prepared by reacting concentrated sulfuric acid with carbon nanotubes (CNTs) on the defect sites. Fourier transform infrared (FTIR) spectroscopy and transmission electron microscopy (TEM) were used to characterize the morphology and structure of sCNTs, respectively. Subsequently, polyaniline (PANI)/nickel hexacyanoferrate (NiHCF)/sCNT interconnected composite films were electrodeposited on the platinum electrode by the one-step co-polymerization using cyclic voltammetry in an aqueous dispersion containing sCNTs. The effect of concentration of NiSO 4 and K 3 Fe(CN) 6 in the prepared solution on the morphology and structure of PANI/NiHCF/sCNTs composite films was studied by scanning electron microscopy (SEM), FTIR spectroscopy, and X-ray diffraction (XRD), respectively. The effect of concentration of NiSO 4 and K 3 Fe(CN) 6 in the prepared solution on polymerization and electrochemical performance was investigated by cyclic voltammetry (CV), galvanostatic charge/ discharge tests, and electrochemical impedance spectroscopy (EIS). One-step electrodeposition mechanism was discussed deeply. It was found that sulfonic acid groups had been attached to surface of CNTs, and sCNTs had higher dispersibility than CNTs in an aqueous dispersion. The morphology of PANI/NiHCF/sCNTs interconnected composite films was remarkably influenced by the concentration of NiSO 4 and K 3 Fe(CN) 6 . The tubular packing structure appeared with the low concentration of NiSO 4 and K 3 Fe(CN) 6 in prepared solution, while the beautiful coral-like interconnected structure exhibited with 0.04 mol L −1 NiSO 4 and 0.04 mol L −1 K 3 Fe(CN) 6 , which was mainly attributed to the π-π* electron stacking effect among sCNTs, NiHCF, and PANI. The specific capacitance and electroactivity of PANI/NiHCF/sCNTs composite films increased markedly with the increase of concentration of NiSO 4 and K 3 Fe(CN) 6 in prepared solution. The specific capacitance of PANI/NiHCF/sCNTs composite film was 430.77 F g −1 with 0.04 mol L −1 NiSO 4 and 0.04 mol L −1 K 3 Fe(CN) 6 due to selfdoping effect of sCNT in composite films. The cycle stability of PANI/NiHCF/sCNTs composite films was enhanced with the increase of NiSO 4 and K 3 Fe(CN) 6 in prepared solution.

“…Among the analogues of Prussian Blue, copper hexacyanoferrate shows a well-defined, reversible and reproducible electrochemical response in supporting electrolytes containing not only potassium but also other alkali metal cations such as lithium, sodium, rubidium or cesium [15][16][17][18], contrary to Prussian Blue that only shows good electroactivity in electrolytes containing K + .…”

A copper containing Prussian Blue analogue was incorporated into a conducting polypyrrole film. The modified electrode was synthesized through an electrochemical two-step methodology leading to very stable and homogeneous hybrid films. These electrodes were proved to show excellent catalytic properties towards H 2 O 2 detection, with a performance higher than those observed for Prussian Blue and other analogues. Electrochemical impedance spectroscopy experiments demonstrated that the excellent performance of these hybrid films is strongly related to the electronic conductivity of the polymeric matrix that is wiring the copper hexacyanoferrate sites. A glucose biosensor was built-up by the immobilization of glucose oxidase; the sensitivity obtained being higher than other biosensors reported in the literature even in Na + containing electrolytes.
